• An electron (mass = $9.1 \times {10^{ - 31}}$ kg; charge = $1.6 \times {10^{ - 19}}$C) experiences no deflection if subjected to an electric field of $3.2 \times {10^5}$V/m, and a magnetic fields of $2.0 \times {10^{ - 3}}$ Wb/m2. Both the fields are normal to the path of electron and to each other. If the electric field is removed, then the electron will revolve in an orbit of radius
